Aug. 9, 1932 E.- H. GRISWOLD TOBACCO PIPE Filed July 26, 1930 Patented Aug. 9, 1932 UNITED-STATES PATENT OFFICE EDWARD H. GRIS WOLD, OF PONCA CITY, OKLAHOMA, ASSIGNOR OF ONE-HALF TO JAMES A. HUDSON, OF PONCA CITY, OKLAHOMA TOBACCO PIPE Application filed July 26,

This invention relates to tobacco pipes for the use of smokers.

The principal object of the invention is to provide a pipe having'means for collecting the heat from the tobacco burning in the bowl and transmitting and radiating that heat into the adjacent air, to the end that the pipe and contents may remain relatively cool and a relativelycool smoke afforded the user.

A further object is to provide a pipe bowl having a plurality of fins projecting from the same in such manner as to serve to collect and radiate the heat from the bowl to the surrounding air.

Still another object is to provide a pipe bowl having means associated therewithfor gathering and radiating heat from tobacco burning in the bowl.

And another object is to provide a pipe having a bowl upon the walls of which are fins adapted to collect and radiate heat from the interior of the bowl.

With the foregoing and such other objects and advantages in view as may appear, attention is called to the following specification and to the accompanying drawing as constituting part thereof, and in which said drawmg Figure 1 is a top plan view of one preferred embodiment of my invention, and wherein the cooling fins are annular and are arranged upon the outer side of the pipe bowl concentrically with the axis of the bowl;

Figure 2 is a vertical longitudinal section 1 through the embodiment as shown in Figure 1; Figure 3 is a top plan view of another embodiment of the invention, and wherein the cooling-fins are straight in form and are arranged-upon the outer side of the pipe bowl in parallelism with the said axis of the bowl;

Figure 4 is a side elevation of the embodiment as shown in Figure 3;

Figure 5 is a top plan view of yet, another embodiment of the invention, and wherein the cooling-fins are of the straight formation as shown in Figures \3 and 4, but are disposed both upon the inner and outer sides of ;th b 1- 5 e plpe ow Figure 6 is a detail in perspective of still 1930. Serial no. 470,813.

anothermodification, wherein the inner and straight form of the fins as shown in Figure 5 are assembled upon rings in the form of a removable cage for insertion within the bowl of the pipe; 7

Figure 7 is a top plan view of the removable fin cage represented in Figure 6, as same would appear mounted within the'pipe bowl, the said bowl bein equipped with the straight outer form 0t fins as represented in Figures 4 and 5. In this view the stem is shown as broken ofl. g 4

In carrying out this invention, I-provide a pipe bowl 1 and which is constructed in con ventional form of any suitable material or substance, and provided with the conventional stem 2. Upon the bowl 1, I arrange a plurality of cooling fins 3 and which may be either annular in form and disposed concentrically with the longitudinal axis of the bowl and upon the outer side thereof, as shown in Figures 1 and 2, or which may be straight in form and arranged radially upon the outer sideof the bowl in parallelism with the axis thereof, as shown in Figures 3 and 4. Or, the fins 3 may be arranged both upon the outer and inner sides of the pipe, as shown in the straight form of the fins in Figure 5. Or,

for facilitating cleaning the pipe, the inner fins may be mounted upon rings 4, as shown in Figure 6, thus forming a removable cagelike structure which may be readily inserted within the bowl, as shown in Figure 7, or removed therefrom when it is desired to clean the pipe.

Obviously, the inner, straight form of the fins may be combined with the outer annular form, or vice versa, as desired.

Whatever the especial form of the fins 3, or other arrangement upon the outer or inner side of the bowl 1, the purpose and function thereof is to facilitate the transmission and radiation of heat from tobacco burning within the bowl to the surrounding air, and thus substantially reduce the heat ofthe pipe as a whole and of the smoke passing through the stem to the mouth of the user. The cooling fins being located upon the bowl, are especially efiicient for their purpose, owing to the fact that they'there have the largest possible ferred forms or embodiments of my invenradiating area, and are located directly; upon the heat creating element so that the-heat from the burning tobacco passes directly out a through the fins. While I have herein described certain pretion, I do not limit myself to the exact structures shown, but reserve the right to vary samein minor details, within the scope of the appended claims.

I claim: 7 1. A pipe bowl, and a. plurality of cooling 4 fins arranged in the form of avcage for removably positioning within the bowl.

2. A pipe bowl, a plurality of rings for removably positioning inthe pipe bowl, and cooling fins secured to the said rings.

3. A cooling assembly for mounting in a pipe bowl comprising an annulus and a plurality of cooling fins secured to the said an nulus. v I

In testimony whereof I aflix my signature.
